Abstract
PURPOSE: To easily mount a punching edge to a mounting shaft, by forming an inclined face part on an upper face part of a punching edge mounting hole. CONSTITUTION: A mounting part 3 of a punching edge A is pushed into a mounting shaft 6 projecting from a lower face of a mounting member 4. On this occasion, an inclined face part 11 is formed on a periphery of an upper face part of the mounting hoe 10 of the punching edge A, and the elasticity is given by a slit 12. Whereby the mounting hole 10 is slightly opened when the punching edge A is strongly pressed to the mounting shaft 6, and a lower edge of the inclined face part 11 of the punching edge A is brought into contact with and bites into an outer periphery of the point part 7 of the mounting shaft 6 having an outer diameter slightly larger than an inner diameter of the mounting hole 10. As the result thereof, the punching edge A is unremovably mounted on the mounting shaft 6.
